SUCTION CLEANING DEVICE.

Application filed July 9, 1915.

and particularly to that type of suction cleaner in which a rigid collecting nozzle is carried by the end of a substantiallycylindrical fan chamber, said nozzle terminating in an inlet mouth whose plane is substantially parallel to the axis of said fan chamber, and said chamber and nozzle being supported by suitable rollers so as to maintain said inlet mouth slightly above and parallel with the floor.

The objects of the invention are the provision of new and improved means for adjusting the elevation of said mouth above the floorwhile maintaining it at all times substantially parallel therewith; the provision of an adjusting device which shall be simple, inexpensive, reliable and easily operated; while further objects and advantages will appear as the description proceeds.

Generally speaking, my invention may be defined as consisting of the combinations and constructions recited in the claims hereto annexed and illustrated in the drawings accompanying and forming a part of this application, wherein Figure 1 is a perspective view of my improved cleaner; Fig. 2 is a section on the line 22 of Fig. 3, the fan casing being shown in elevation; Fig. 3 is a bottom plan view of said nozzle; Fig. 4 is a detailed view in section on the line l4 of Fig. 2.

showing the connection between the adjusting lever and the rock shaft.

Describing the parts by reference characters, 1 represents the fan casing of the portable suction cleaner, 2 the motor casing axially secured thereto, 3 the collecting nozzle which projects obliquely forward from the end of the fan casing opposite the motor, said nozzle increasing in Width as it departs from said fan casing, and being formed at its extremity with a pair, of spaced parallel jaws, 4, 5, defining an elongated inlet mouth. Said nozzle is supported by meansof suitable rollers 66,

and the rearward part of the machine by means of a suitable roller 7, the former rollers being journaled to the rock shaft 8 which is pivoted upon an axis eccentric to the axes of the rollers.

The nozzle is substantially triangular in shape and embodies the bottom plate 10 and top plate 11 and'the interior of this nozzle is divided into two separate passageways by means of interior wall or walls 13.

The bottom plate 13 defines a hollow open space and the wall 10 is discontinued inside of this space forming an open recess 14 which is traversed by the shaft 8 asshown in F ig.'3. The upper side of said recess is closed by a web 15 formed with a slot 16 one side of which is formed with one or more notches 17. Pivoted to the shaft 8 upon a transverse axis is a radial arm 18 whose end projects through the slot 16 and is held in engagement with the desired notch by means of a suitable spring 19.

With this arrangement it is possible to adjust the vertical height of the inlet mouth without inverting the cleaner or otherwise disturbing its position, while the adjustment of the supporting members near the mouth reduces the angular motion to a minimum. I have shown the nozzle formed with the inlet-mouth having an elongated hollow chamber whose roof is provided with the rib or wall 20 and the brushing mechanism 21 located at one side of said rib. The particular construction of the inlet mouth has no bearing upon the adjusting mechanism here shown excepting that with a wide mouth it is particularly important to effect a Vertical adjustment of the cleaner without angular movement.

While .1 have described my invention in detail I do not limit myself to such details except as the same may be positively included in the claims hereto annexed or may be rendered necessary by the prior state of the art.

Having thus described my invention, what I claim is 1. In a suction cleaner, a nozzle having Walls therein with a recess between said walls, an adjustable support for said nozzle, and an operating device connected to said support and projecting into the recess and adapted to adjust said support to raise or lower the nozzle.

2. In a suction cleaner, a nozzle, an adjustable support for said nozzle, adapted to support the same upon a floor, and an operating member connected to said support and extending through the nozzle and adapted to adjust said support to raise or lower the nozzle.

3. In a suction cleaner, a nozzle having a recess extending through the same, a wheeled crank axle under the nozzle and supporting the same, and an adjusting arm connected to said axle and projecting through said recess to the upper side of the nozzle.

4. In a suction cleaner, a casing having a pump chamber and a fan shaped collecting nozzle projecting therefrom, a wall connecting the top and the bottom walls of said nozzle and spaced from both side walls, the top and bottom walls being discontinued within said partition whereby a recess is provided, a slotted Web traversing said recess, an axle pivoted below said nozzle and having offset ends, rollers journaled on said ends, and an adjusting armcarried by said axle and projecting through the slot.

5. In a suction cleaner, a casing having a pump chamber and a fan shaped collecting nozzle projecting therefrom, a wall connecting the top and the bottom walls of said nozzle and spaced from both side walls, the top and bottom walls being discontinued within said partition whereby a recess is provided, an axle pivoted below said nozzle and having offset ends, rollers journaled on said ends, an adjusting arm carriedby said axle and projecting through said recess, and means for securing said arm in different angular positions Within said recess.

6. In a suction cleaner, a casing having a fan shaped collecting nozzle, said nozzle comprising upper and lower spaced walls defining a suction passage therebetween-and terminating at their lower ends in an inlet mouth, a wall connecting said upper and lower walls and forming a recess, a web traversing said recessv and having an elongated slot therein, a rock shaft journaled beneath said nozzle upon an axis transverse to said machine, a yielding arm projecting radially from said shaft and projecting through said slot, the edges of said slot being 1 formed with spaced notches for the reception of said arm, and floor engaging rollers journaled upon said shaft, one at each side or" said nozzle, the roller carrying portions ,of said shaft being ofiset relatively to'the portions thereof which are journaled to said nozzle.

In testimony whereof, I hereunto aflix my signature in the presence of two witnesses.
